Overview
The HMC442LM1TR is a broadband GaAs PHEMT MMIC Medium Power Amplifier produced by Analog Devices Inc. This amplifier operates within the frequency range of 17.5 to 24 GHz and is packaged in a surface mount (SMT) leadless chip carrier. It is designed to offer low loss and excellent input/output (I/O) match, preserving the performance of the MMIC chip. The HMC442LM1TR provides 14 dB of gain and +23 dBm of saturated power at 27% Power Added Efficiency (PAE) from a +5V supply voltage.
